Our take
As individuals and communities look to lower the carbon footprints of their buildings and homes, there is a need to access products and infrastructure that will enable them to adopt more eco-friendly energy practices. 1KOMMA5° is building a "one-stop shop" for sales, installation and services related to solar, power storage, and EV charging infrastructure, simplifying the energy transition for carbon-conscious people.
1KOMMA5°'s offerings include the energy manager "Heartbeat", a free-to-use platform that can be accessed on mobile, and helps users to make the most out of their self-generated electricity. The company is also building a group of experienced specialist companies that it aims to support in aiding the clean energy transition, not only by investing in them but by granting them access to its operational experience to help them further develop.
A 2024 surge in revenue and profitability (leading to the company's unicorn status in 2023) underscores the market's confidence in 1KOMMA5°'s transformative potential. With a clear trajectory towards exponential growth, fueled by ambitious revenue targets and strategic investments in product development, the company is poised to redefine the energy sector.
